COMBlNEDSHEARS AND KNIFE.

SPECIFICATION forming part of Letters Patent N 0. 631,403, dated August 22, 1899.

Application filed May 31, 1899. Serial No. 718,849. (No model.)

To all whom it 'lI'l/U/Z/ colwcrlt:

Be it known that LARTHUR S. E. METCALF, a citizen of the United States, residing at Amberg, in the county of Marinette and State of Visconsin, haveinvented a new and useful Combined Shears and Knife, of which the following is a specification.

. formation of proper cutting edges on the knife and shears, one of said hear-blades having, moreover, a file upon its rear edge.

A further object of my invention is to provide a new and efficient arrangement of stopsprings for holding the foldable elements in their adjusted positions.

The invention consists of two handle elements pivotally connected,and upon the pivot of these elements are rotatably mounted two shear-blades and a knife-blade, said blades having individual stop-springs, the fixed ends of which are passed through openings in their respective handles to hold them immovably.

I11 the drawings forming a portion of this specification, and in which like characters of reference designate similar parts in the several views, Figure 1 is a perspective View of my implement with the shear-blades in opposite positions and open. Fig. 2 is a perspective view of my implement with the knife-blade distended and the shear-blades and handles closely folded. Fig. 3 is an elevation showing the handles separated and the cutting blades extending at different angles intermediate their folded and unfolded positions. Fig. 4 is a View showing the handle element which carries both the knife-blade and one of the shear-blades.

Referring now to the drawings, in operating in accordance with my invention I form two similar handle elements 7 and 20,having loops 5 at their rear ends for the reception of the thumb and finger or fingers of the opera tor. One of the handle elements 7 has a perforation adjacent its forward end, through which is passed a pivot-pin 9, having mounted thereon adjacent the face of the handle a knife-blade 10, at the rear end of the back of which is formed a recess adapted to receive the adjacent end of a stop-spring 11, having a perforated lug 12, through which is passed a pin 13, engaging the handle 7 and forming a means of attachment of the spring 11 thereto. The rear end ofspring 11 extends through a recess 14, formed in the adjacent edge of the handle 7, in. which recess it is held in a manner to be presently described. The op eration of the spring 11, in connection with the blade 10, is the same as in an ordinary pocket-knife and is well understood.

Mounted upon the pivot-pin 9 is a shearblade 15, having at the end of its rear edge a recess 16. in which is seated the free end of a stop-spring 17, having a perforated lug 18,

through the medium of which perforation it is mounted upon the pin 13, said spring passing into the recess 14 and having its end disposed between the adjacent end of spring 11 and the end Wall 19 of said recess. The springs 11 and 17 conform to the outline of the adjacent edge of the handle 7, and the ex tremities of the ends lying in the recess 14 are dressed off flush with the outer surface of the handle. In conformity with the wellknown operation of stop-springs in pocketknives the springs 11 and 17 in bearing against the adjacent shoulders of the slots in the rear edges of their respective blades prevent the backward bending or movement of their blades and at the same time hold said blades against falling forwardly and also against acshear-blade 15 and the handle 20, the two shear-blades being in direct engagement and so arranged that when they are distended they will codperate after the manner of the usual construction of shears. A stop-spring 22 is connected with the handle 20 through the medium of a pin 23, passed through a lug 24 ofsaid spring, the free end of the spring ongaging a recess at the rear end of its respective shear-blade, the opposite end of the spring lying in a recess in the rear edge of the.

handle and engaging the end wall 25 of the latter. It will be understood that the end walls 19 and 25 of the recesses in the handles are beveled to prevent outward springing of the stop-springs. Thus it will be seen that when desired the knife-blade may be folded against its handle element 7, as shown in Fig. 1 of the drawings, and that the shearblades and 21 will then be capable of operation inthe manner of ordinary shears and may be given their correct cutting edges; also that, as shown in Fig. 2 of the drawings, when desired the shear-blades may be folded against their respective handles and that the knife-blade may be distended into a position ready for operation, said knife-blade having its proper form of cutting edge, which, as is well known, is entirely different from the cutting edge of a shear-blade.

It will be readily understood that I may construct my device of any dimensions and that I may vary the general style and appearance thereof withou tdeparting from the spirit of my invention.

Having thus described the invention, what is claimed is 1. A device of the class described comprising handles pivotallyconnected, shear-blades pivoted to said handles, and a knife-blade mounted upon the pivot of the first-named blades and adapted to be distended with respect to the handles and interchangeably with the shear-blades.

2. A device of the class described comprising handles pivotally connected, shear-blades pivotally mounted upon the pivot of said handles and adapted to be folded thereagainst and distended therefrom, and a knife-blade mounted upon said pivot and adapted to be folded against and distended from said handles interchangeably with the shear-blades.

3. The combination with a handle having a recess formed transversely thereof, of a blade pivoted in said handle, and a stop-spring carried by the handle, engaging said blade, and having one end bent to lie in said recess.

4. The combination with two handles pivotally connected, of two shear-blades mutually adjacent and mounted upon the pivot of said handles, a knife-blade mounted also upon said pivot, and a stop-spring for each of said blades and adapted to hold them at diiferent points in their pivotal movement.

5. The combination with a handle having a transverse recess therein, and a resultant end shoulder, of a plurality of blades pivotally connected with the handle, a stop-spring for each blade, the ends of said springs being bent to lie in said recess, one upon another, the adjacent spring engaging said end shoulder to hold the springs therein.

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two witnesses.
